TECHNICAL FIELD

The invention relates to systems, methods and apparatus for multi-player gaming. In particular, the multi-player gaming involves a common display visible to multiple players while each of a plurality of game controllers is controlled by a respective player associated with a particular game character.

BACKGROUND

In a multi-player game environment where a large number of users can play an interactive action-based game on a single large display screen, such as that which may be found in a cinema, for example, it may be difficult for one of a large number of players to identify his or her onscreen character (or avatar) amongst all of the characters of the other players on the screen. This difficulty would be increased if the game characters chosen by the various players look similar to each other.

If a player is not easily (or readily) able to identify his or her game character on the large screen, the player's enjoyment of, and thus incentive to play, the game may be diminished.

A further problem in such a multi-player game environment arises in relation to receiving game input commands from all of the large number of players. In an existing cinema or other large arena, for example, it may not always be cost-effective or practical to provide cabling or wiring to a large number of player input terminals for receiving the player input commands.

It is desired to address or ameliorate one or more shortcomings of existing multi-player gaming systems, or to at least provide a useful alternative to the prior art.

SUMMARY

Aspects of the invention relate to systems and methods for multi-player gaming. Some aspects relate to systems having an improved communications infrastructure and improved handheld game controllers, while other aspects relate to improvements in handling large numbers of players in the multi-player game, for example, by enabling easy identification of a player's on-screen character (or avatar) or by providing a pre-game activity on the handheld game controller prior to allowing a player to join the multi-player game. Yet other aspects relate to methods of multi-player gaming and player registration for a multi-player game.

In one aspect, the invention relates to a multi-player bingo game system comprising:

a bingo game server configured to provide display signals for displaying a multi-player bingo game;

a display system having primary display means, the display system being configured to provide a primary bingo game display of the multi-player bingo game on the primary display means in response to the display signals;

a plurality of game controllers, each bingo game controller having secondary display means for providing a secondary bingo game display and input means for receiving player input; and

communication means for enabling communication between the game server and each of the plurality of bingo game controllers;

wherein the plurality of bingo game controllers are located in proximity to the primary display means such that the primary display means is visible to bingo game players manipulating respective bingo game controllers.

The primary display means may include a large display screen, for example of a size which is used in cinemas. The large display screen may be a projection screen, in which case the display system includes a projector to project an image of the multi-player bingo game on the display screen. The display system may use projection equipment which is normally used for projecting films if that equipment is configured to project digital images.

The bingo game controllers may be small handheld computing devices with wireless transmitter means for communicating with the bingo game server. Alternatively, the handheld computing devices may be in wired communication with the bingo game server over a network, such as an Ethernet.

In one embodiment, each handheld computing device receives power from an external source, such as an externally mounted battery pack. The handheld computing devices may be each connected to an arm of a seat or to another fixed structure in the bingo game arena.

The battery pack may be removably mounted to the seat arm or other fixed structure, while the handheld computing device is connected to the seat arm or other structure by means of a tether. The tether comprises a movable connection means for allowing the handheld computing device to move relative to the seat arm or other structure and houses a power cable for supplying power to the handheld computing device from the battery pack. The tether may comprise a rigid connecting arm or may comprise a flexible retractable cable.

The bingo game arena may be in an enclosed theatre, such as a movie theatre, or it may be another kind of venue, such as an outside amphitheatre, convention hall, meeting room or other suitably large place that has a suitable display system and communications infrastructure enabling communication between the bingo game controllers and the bingo game server. The bingo game arena may be a venue specifically designed for multi-player bingo gaming such as a bingo club.

The bingo game arena may have a large number of seats (for example, in the order of fifty to a few hundred seats) facing the display screen so that the players can face the display screen and hold the secondary display of the bingo game controller within view, while seated in the seats in the bingo game arena.

The bingo game system may support up to a few hundred bingo game controllers so that, in a bingo game arena having a potential occupancy of a few hundred people, almost every person may participate in the multi-player bingo game, if desired or allowed.

Each bingo game controller may comprise player input means. The display screen of the bingo game controller may be formed as a touch screen, by which the user can provide input by touching portions of the display screen. The bingo game controller may also have a card reader, for example in the form of a smart card slot or magnetic strip reader, for authenticating a player for participation in the bingo game.

The communication means may include a communication controller in communication with the bingo game server over a high-speed interface and having at least one wireless arena transceiver. Each bingo game controller also has a wireless game controller transceiver module, forming part of the communication means, to receive signals from the at least one wireless arena tranceiver and transmit signals back to the bingo game server via the at least one wireless arena transceiver. In order to enable effective communication between the bingo game controllers and the bingo game server, the at least one wireless arena transceiver is located within the bingo game arena. The bingo game server and communication controller need not be located in the bingo game arena.

The at least one wireless arena transceiver may be located on a ceiling or upper sidewall portion of the bingo game arena, generally toward the display screen or may be located in a spaced configuration around the bingo game arena.

The bingo game server may be further configured to enable one or more supplementary game activities in conjunction with the display system and the bingo game controllers. These may include trivia-based games and/or word-based games.

In a further aspect, the invention relates to a method of player registration for playing a multi-player bingo game. Player registration is initiated by each prospective player of the multi-player bingo game by inputting a payment authorization code, which may be an account code, into a handheld bingo game controller. The payment authorization code may be received from a built-in card reader, where a card having the code stored thereon is passed through or into the card reader, or by manual input. The handheld bingo game controller tries to validate the payment authorization code and, if valid, encrypts the code and sends it to a bingo game server that facilitates the multi-player bingo game. The bingo game server decrypts the code and attempts to recognize it as pertaining to an existing (pre-registered) account useable for paying for the multi-player bingo game. If the bingo game server recognizes the decrypted code, it checks whether there are sufficient funds in the account to allow the player to play the multi-player bingo game. If sufficient funds exist on the account, the account is debited for an appropriate amount and the player becomes registered to play the multi-player bingo game. The handheld bingo game controller is then unlocked for use by the player for playing the multi-player bingo game (or for performing another activity) and relevant bingo game software is downloaded from the bingo game server to the handheld bingo game controller to enable the player to participate in the multi-player bingo game by manipulating the handheld bingo game controller.

The method of player registration may be performed in conjunction with a multi-player bingo game system having a display system and arranged in a bingo game arena. The bingo game arena includes a plurality of the handheld bingo game controllers, the display system and wireless communication means for enabling the handheld bingo game controllers to communicate with the bingo game server.

In a still further aspect, the invention relates to a method of conducting a multi-player bingo game. The method involves receiving at a bingo game server a plurality of registration requests from respective bingo game controllers manipulated by prospective players of the multi-player bingo game. The registration requests are processed so as to register eligible prospective players as registered players of the multi-player bingo game. A number of registered players are added to the multi-player bingo game, up to a predetermined number of players and the bingo game is then begun. During play of the multi-player bingo game, one or more registered players previously added to the bingo game are removed from the bingo game in response to one or more predetermined bingo game removal events. Once registered players have been removed from the bingo game, a corresponding number of registered players are added to the bingo game so that the number of registered players playing the multi-player bingo game does not exceed the predetermined number of players. Once a predetermined bingo game end event occurs, the multi-player bingo game is ended. One or more of the players may be declared to be the winner or winners, following the end of the bingo game, depending on the achievements of the registered players during play of the multi-player bingo game.

The multi-player bingo game may be displayed on a large display screen in a bingo game arena housing the bingo game controllers and the registered players. The one or more predetermined bingo game end events may include expiry of a predetermined game time or the fulfillment of a winning criteria by one or more of the players.

Following the registration of eligible prospective players (where eligibility is determined at least partly on the basis of successful payment for the multi-player bingo game), the bingo game server may download a bingo game module to each bingo game controller for facilitating play of the multi-player bingo game. Alternatively, the bingo game module may be pre-loaded into the bingo game controllers and enabled once registration is complete.

Further aspects of the invention relate to computer readable storage media having stored therein computer program instructions which, when executed by one or more processors, cause the one or more processors to perform any one of the methods described herein.

Further aspects of the invention relate to methods of facilitating team play in a multi-player bingo game. In one such aspect, a plurality of handheld bingo game controllers are provided in a bingo game arena. The handheld bingo game controllers each has input means for receiving player input from respective players and a first display screen for displaying bingo game-related images. A bingo game server is also provided in communication with the handheld bingo game controllers for receiving first signals from each handheld bingo game controller and for transmitting second signals to the handheld bingo game controllers. The first signals correspond at least in part to player input received at the respective hand held bingo game controller.

In response to player input from a first player, the bingo game server receives a team creation request from a first handheld bingo game controller. In response to the team creation request, the bingo game server creates a team entry in a team table maintained by the bingo game server. The bingo game server then adds a player entry for the first player to the team entry. In response to player input from a second player, the bingo game server receives a team join request from a second handheld bingo game controller. In response to the team join request, the bingo game server adds a player entry for the second player to the team entry. A team can then be formed on the basis of the team entry and the multi-player bingo game then started. Once the multi-player bingo game is started, the bingo game server causes bingo game images of the multi-player bingo game to be displayed on a second display screen.

The bingo game may receive multiple team join requests from multiple players and may add player entries to the team entry, optionally only if the first player consents to those players joining the team. The team may have a predetermined limited number of team positions, for example such as 4 or 6.

In another aspect, the invention relates to a multi-player bingo game system comprising: a bingo game server configured to provide display signals for displaying a multi-player bingo game; a display system having primary display means, the display system being configured to provide a primary bingo game display of the multi-player bingo game on the primary display means in response to the display signals; a plurality of bingo game controllers, each bingo game controller having input means for receiving player input relating to the multi-player bingo game, the plurality of bingo game controllers being located in proximity to the primary display means such that the primary bingo game display is visible to bingo game players manipulating respective bingo game controllers; communication means for enabling communication between the bingo game server and each of the plurality of bingo game controllers; and at least one remote bingo game controller located remotely from the primary display means and having secondary display means for displaying a secondary bingo game display of the multi-player bingo game and input means for receiving player input relating to the multi-player bingo game, the at least one remote bingo game controller being in communication with the bingo game server over a network.

The at least one remote bingo game controller may communicate with the bingo game server over a cable television communications link or using a digital television service delivered using an internet protocol.

DETAILED DESCRIPTION OF EMBODIMENTS

Embodiments of the invention are hereinafter described in further detail, by way of example only, with reference to the accompanying drawings. In the following description, like reference numerals will be used to indicate like, similar or corresponding features, functions or elements as between the drawings and embodiments depicted therein.

Embodiments of the invention relate to methods and systems for multi-player gaming. In the following description of these embodiments, certain aspects of the embodiments are described separately. For example, the system architecture is described separately to the example game implementations and game software. It should be understood, however, that each of these aspects forms at least part of the described embodiments.

Multi-Player Gaming System Architecture

Referring now to FIGS. 1, 2, 3 and 4, system architecture aspects of the multi-player gaming system will now be described. FIG. 1 shows a multi-player gaming system 100 according to one embodiment of the invention, comprising a game server 110, a communications controller 115 and a game arena 120.

The game server 110 stores and runs game software 310 for facilitating the multi-player game. The game server 110 interfaces with the game arena 120 through communications controller 115, which controls high speed wireless (radio frequency) communication within the game arena 120 and high speed wired communications to and from the game server 110. Game arena 120 comprises a display system 125, a wireless transmitter 130, a plurality of handheld game controllers 135 and at least one (up to, say, 6) wireless receiver 140.

The game arena 120 may be a large indoor screening area 400, such as a cinema, theatre, conference hall, presentation hall or the like. Alternatively, the game arena 120 may be an outdoor facility, such as an amphitheatre, stadium or other outdoor area where the attention of participants can be focused on a large central display.

Display system 125 is disposed within the game arena 120 and comprises a projector and a large display screen upon which images of the multi-player game are displayed when the game is being played. The projector may be of a kind normally used for digital projection of films in a cinema. An example of a suitable projector is the Wide XGA Digital Multimedia Projector by Sanyo, model PLV-WF10.

The display screen (shown in FIG. 4 and designated by reference numeral 425) may be any suitable screen for displaying images thereon, for example such as a movie screen or other flat or substantially planar surface of suitable reflectivity for viewing video images. The display screen may comprise a wall or part thereof, depending on the physical characteristics of the game arena 120.

The game arena 120 is intended to accommodate a relatively large number of handheld game controllers 135, for example in the order of 20 to 250 handheld game controllers 135. Each handheld game controller 135 is used by an individual player of the multi-player game while seated, or otherwise located, within the game arena 120. For example, each handheld game controller 135 may be associated with a seat facing the large display screen 425 so that players of the multi-player game can sit in seats in the game arena 120 and manipulate the handheld game controllers 135 while viewing a display of the multi-player game on display screen 425. The components and operation of handheld game controllers 135 are described in further detail below.

The game system 100 shown in FIG. 1 is an embodiment in which the multi-player game may be performed in a single game arena 120. In another embodiment, such as is shown in FIG. 2, a number of multi-player games may be performed in separate game arenas 120, located relatively near each other or remotely from each other.

In the embodiment shown in FIG. 2, each multi-player game system 100 has a game server 110, communications controller 115 and game arena 120, as described above in relation to FIG. 1. Each of these multi-player game systems 100 may be included within a larger multi-arena game system 200. The multi-arena game system 200 comprises an administrative server system 210 in communication with the game servers 110 of each of the multi-player game systems 100, as well as a payment/authentication system 220 for player authentication and payment processing.

The administrative server system 210 performs overall system administration functions, as well as facilitating communications between game servers 110 of different multi-player game systems 100. For example, administrative server system 210 may keep a register of players who have chosen to provide registration information prior to playing a game and/or as part of providing payment information. The administrative server system 210 is also configured to perform non-game specific functions. For example, the administrative server system 210 logs statistics, such as the average number of players, the average length of play time and the average spend of each player, in order to assist in analyzing system performance and customer usage.

In one embodiment, game arenas 120 within the multi-arena game system 200 may be adjacent cinemas within a cinema complex. In such a case, wireless communications from one game arena 120 may cross over into an adjacent game arena 120, causing interference or disruption to the multi-player game.

In order to avoid transmission of game data at the same time in adjacent game arenas 120, a communications clock signal 230 is employed so as to synchronize the communications controllers 115 of all multi-player game systems 100 within multi-arena game system 200. Thus adjacent game arenas 120 are controlled so as to not transmit game data at the same time. Instead, a clock cycle of, say 40 Hertz, is used to allocate a transmission period of 12.5 milliseconds for communications within one or more separated game arenas 120. Once that 12.5 millisecond period passes, adjacent game arenas 120 are allowed to transmit for a subsequent period of 12.5 milliseconds. If significantly fewer handheld game controllers 135 than the maximum (256) are in use, say less than 128, the transmission period may be doubled or otherwise increased.

For clocking purposes, one communications controller 115 is designated by administrative server system 210 to provide the master communications clock signal 230 from which other communications controllers 115 follow, to coordinate transmission timing. A dedicated clock cable, for example such as a twisted pair, is provided for communicating the master communications clock signal 230.

Depending on the number and physical arrangement of the multiple game arenas 120 within multi-arena game system 200, the communications clock 230 can be used to ensure that immediately adjacent game arenas 120 do not transmit data at the same time, while allowing game arenas 120 that are sufficiently remote from each other to transmit simultaneously (as there is less chance of interference in such a case). Alternatively, if each game arena 120 has sufficient electromagnetic shielding to sufficiently reduce the likelihood of interference from adjacent game arenas 120, the communications clock 230 may be unnecessary and the data communications rate within each game arena 120 would not need to be reduced.

FIG. 2 shows a multi-arena game system 200 having three multi-player game systems 100. It should be understood, however, that there may be any number of multi-player game systems 100 within multi-arena game system 200. For example, a cinema complex may host ten multi-player games in ten different theatres, with each theatre being a game arena 120 of a multi-player game system 100, within an overall multi-arena game system 200. Further, cinema complexes at different locations may be governed by the same multi-arena game system 200, sharing a single administrative server system 210.

While multi-arena game system 200 is shown having multiple multi-player game systems 100, an alternate embodiment provides a single multi-player game system 100 operating with its own administrative server system 210 and payment/authentication system 220. This embodiment may be more suitable where only one game arena 120 can be accommodated at a certain location.

Referring now to FIG. 3, the game server 110 is described in further detail. Game server 110 accesses computer program instructions in the form of game software 310 stored in memory 312. The game software 310 is loaded from memory 312 and processed by a computer processor (not shown). The game server 110 also comprises a display driver 314 responsive to instructions from game software 310 for providing display instructions to display system 125. Game server 110 further comprises a game controller driver 316 for providing game data to, and receiving player command data from, handheld game controllers 135 via communications controller 115.

The game software 310 running on game server 110 may vary according to the desired game to be played on multi-player game system 100. The appropriate software may be loaded from memory 312 in response to votes cast by players when initiating the multi-player game or in response to a selection by an administrative operator of game server 110 or administrative server system 210.

When the game to be played has been selected and game software 310 is loaded from memory 312, game server 110 downloads a game software module to each of the handheld game controllers 135 via communications controller 115 prior to initiation of the multi-player game. This download may take several minutes but is necessary in order to enable a complimentary display to be provided on the display screen of the handheld game controller 135 during operation of the multi-player game.

The game software module thus downloaded from game server 110 onto handheld game controller 135 may also include software to enable activities not directly related to the multi-player game, such as a pre-game qualification activity, to be performed. Alternatively, in response to a request from the player, game server 110 may download to the handheld game controller 135 a game software module for a game other than the multi-player game, to be played by the player as a single player game, thus enabling a player to opt out of the multi-player game if it is not of interest to him/her.

Each handheld game controller 135 is provided with suitable software stored in memory for accomplishing certain basic functions, such as processing (including encrypting) payment authorization information received from a player prior to commencement of a game. This pre-loaded software may also include a browser application for enabling Internet or other more restricted network browsing, such as of a theater intranet. Intranet browsing in such a manner advantageously allows the person browsing to preview upcoming films, games, promotions and other forms of product or service marketing. Also, the handheld game controllers 135 may have video images or static images pre-loaded into memory, for example, so that a person manipulating one of the handheld game controllers 135 can view (on display screen 640) advertisements for upcoming films or games or other products or services.

Referring again to FIG. 1, wireless transmitter 130 and wireless receivers 140 include suitable hardware and/or software modules for wireless communications at radio frequencies with handheld game controllers 135. The communications controller 115 comprises a high-speed serial interface for communicating data to transmitter 130 for transmission to the handheld game controllers 135 and for receiving command data from the handheld game controllers 135 via wireless receivers 140.

Communications controller 115 is configured to transmit data packets to the handheld game controllers 135 at a rate of up to 1 megabit per second via wireless transmitter 130 using a transmission frequency of about 2.4 gigahertz.

It should be understood that transmission rates and communications infrastructure described herein are exemplary only, as it is anticipated that improved transmission rates and communication infrastructures will be available in future. Thus, while the communications infrastructure described herein is presently considered to provide high-speed communications, such infrastructure may not be considered high speed by future standards.

Communications controller 115 communicates the received command data to, and receives game data from, game server 110 over a high-speed wired connection, possibly having at least a 10-megabit per second transmission rate in either direction. A suitable connection between the game server 110 and communications controller 115 is an Ethernet connection.

Wireless transmitter 130 comprises suitable RF transceiver, controller, amplifier and antenna hardware modules (not shown) for high-speed wireless data transmission. An example RF module is RF Waves RFW-D100 Link Manager with an RFW112-M transceiver. The transmitter antenna of wireless transmitter 130 provides a directional broadcast of the data signal into game arena 120.

Wireless receivers 140 each comprise a similar RF receiver module, including antenna, amplifier, controller and transceiver hardware modules. Command data transmitted by the handheld game controllers 135 is received by the receiver antenna of each wireless receiver 140. Depending on the location of each wireless receiver 140 relative to the handheld game controllers 135 within game arena 120, one wireless receiver 140 may receive a stronger signal from a particular handheld game controller 135 or that signal may be received at that wireless receiver 140 slightly earlier than at other wireless receivers 140.

Command data transmitted from handheld game controllers 135 is received at wireless receiver 140, which then outputs the command data to the high-speed serial interface in communications controller 115, which in turn provides that data to game server 110.

Data is communicated between the handheld game controllers 135 and the game server 110 in the form of packets. Depending on the purpose of the communication, the number of bytes in each packet may vary. The types of packets include at least the following: a polling packet from the game server 110 to a particular handheld game controller 135; a standard response packet from the handheld game controller 135 to the game server 110, providing data corresponding to any input received from the player; and an interrogation response packet provided from the handheld game controller 135 to the game server 110, sent in response to an interrogation packet received from the game server 110. Other data packet structures may be used to transmit game/command data and information not specifically related to the multi-player game, such as registration-related information or for data or software downloads.

Because wireless data transmissions experience attenuation and are affected by noise, all data communications between the game server 110 and the handheld game controllers 135 include some form of error detection code, for example such as a checksum byte or cyclic redundancy code.

Game controller driver 316 (shown in FIG. 3) includes an input buffer (not shown) and an output buffer (not shown) for receipt and transmission, respectively, of data from and to each handheld game controller 135. Separate input and output buffers are dedicated for communications with each handheld game controller 135 for which a player is registered. Tables 1-3 below illustrate an exemplary packet structure for each of the polling, standard response and interrogation response packets.

The polling packet, as exemplified in Table 1, is transmitted by the game server 110 within the transmission period allowed by the master communications clock 230 (for example, 12.5 ms). The polling packet includes six bytes for communicating a command, an arena identifier, a game controller identifier, a data payload of two or three bytes and a checksum byte. TABLE 1 Polling Packet Data (8 bits) Comments Byte 1 CCCTTTTT C = command T = Arena ID Byte 2 DDDDDDDD D = Controller ID Byte 3 11111111 Data 1 (Extended command if CCC bits = 000) Byte 4 22222222 Data 2 Byte 5 33333333 Data 3 Byte 6 SSSSSSSS Check sum of 1-5 (+controller ID or 0x0FF if error)

The handheld game controller 135 ignores the polling packet if the checksum is incorrect. If the checksum byte is correct, the handheld game controller 135 responds with a five-byte standard response packet that specifies the current state of the handheld game controller 135. If the current state of the handheld game controller 135 is normal, the controller ID is added into the checksum. If not, an error code, such as 0x0FF (255 decimal), is added to the checksum. TABLE 2 Standard Response Packet Data (8 bits) Comments Byte 1 KKKKKKKK Key matrix bits 1-8 Byte 2 XXXXXXXX Joystick X-axis position Byte 3 YYYYYYYY Joystick Y-axis position Byte 4 -KTTTTTT Key matrix bit 9, touchpad 1-7 Byte 5 SSSSSSSS Check sum of 1-4 (+controller ID or 0x0FF if error)

The interrogation response packet (exemplified in Table 3) is a five-byte packet providing status information of the handheld game controller 135 in response to a status request (interrogate packet) from the game server 110. TABLE 3 Interrogation Response Packet Data (8 bits) Comments Byte 1 DDDDDDDD Data 1 Byte 2 DDDDDDDD Data 2 Byte 3 DDDDDDDD Data 3 Byte 4 DDDDDDDD Data 4 Byte 5 SSSSSSSS Check sum of 1-4 (+controller ID or 0x0FF if error)

A processor 605 (shown in FIG. 6) of handheld game controller 135 is configured to parse the polling packet, once received through RF transceiver 615, and to determine the command encoded within the polling packet. Processor 605 responds according to the command received, including, where necessary, constructing a standard response packet or an interrogation response packet. When handheld game controller 135 is receiving a data download from game server 110, processor 605 parses the downloaded packets and stores the software thus received, but does not provide a response, other than simple acknowledgement of the packets received.

The game controller driver 316 maintains an input and output buffer (exemplified in Tables 4 and 5, respectively, below) for each handheld game controller 135. The input buffer holds the last data received from the handheld game controller 135, as well as newly received data not yet parsed. The input buffer also tracks the current state of the various inputs and changes of state of those inputs. The output buffer holds the next data packet to be sent to the controller. Each input and output buffer is duplicated so that one buffer may be sending or receiving while the other is being accessed by the game server 110.

As shown in FIG. 4, game arena 120 has located therein wireless transmitter 130, wireless receivers 140, a plurality of handheld game controllers 135 and display system 125 (which comprises projector 428 and display screen 425). These components of game arena 120 are disposed at various locations around screening area 400.

Wireless transmitter 130 may be located on or near a ceiling of the screening area and has a targeted directional broadcast 430 generally directed towards the seating areas of screening area 400 where players are likely to position themselves while playing the multi-player game. A beam angle θ of directional broadcast 430 may be about 45 degrees to 90 degrees, depending on the physical configuration of screening area 400 and location of wireless transmitter 130. Broader or narrower broadcast angles can be used to accommodate more unusual configurations of screening area 400.

Wireless receivers 140 may be spaced apart along the ceiling of screening area 400 in several positions for receiving output signals from wireless transceivers of handheld game controllers 135. One or more wireless receivers 140 may also be located on a back or side wall of screening area 400, if considered desirable for optimizing signal-to-noise characteristics at the wireless receives 140.

Screening area 400, as exemplified in FIG. 4, may take the form of a cinema or auditorium or another kind of large enclosed space. In such a screening area, it is common to have projector 428 located toward or behind a back wall of the screening area 400 so that the images projected therefrom are directed toward display screen 425 at the front of screening area 400. Alternative locations of projector 428 may be employed, however, to suit the physical layout of screening area 400. For example, projector 428 may be mounted on a structure suspended from the ceiling or protruding from the floor.

In one embodiment, it is preferred to locate the wireless transmitter 130 generally towards the display screen 425, with the directional broadcast 430 being directed somewhat away from the display screen 425, such that the beam angle θ is directed generally downwardly and toward the back of screening area 400. In this arrangement, wireless receivers 140 are located toward the back of screening area 400 so as to be out of a direct line of sight of directional broadcast 430 from wireless transmitter 130. In this arrangement, wireless transmitter 130 may be located within one third of the ceiling area of screening area 400 closest to display screen 425, while wireless receivers 140 may be located within one half of the ceiling or side wall area of screening area 400 toward the projector 428.

In an alternative embodiment, wireless transmitter 130 may be located toward the back of screening area 400 and have directional broadcast 430 oriented generally toward the front and downwardly (but still directed to the seating area where the handheld game controllers will be located during play). With such an arrangement, wireless receivers 140 are located in closer proximity to display screen 425 and generally away from wireless transmitter 130.

In the various embodiments, the precise location of wireless transmitter 130 and wireless receivers 140 within screening area 400 will depend on the physical configuration of screening area 400 to be used in multi-player game system 100. Keeping in mind the need for direct and efficient communication from wireless transmitter 130 to handheld game controllers 135 positioned within a screening area 400 and for a fast and efficient communication from handheld game controllers 135 to wireless receivers 140, some variation or modification of the positioning of the wireless transmitter 130 and wireless receivers 140 may be made.

In an alternative embodiment of the multiplayer game system, designated by reference numeral 1300, the handheld game controllers may be in communication with game server 110 in a wired manner, such as is shown in FIG. 13. Communication between the handheld game controllers and the game server 110 may be performed over a wired network 1350, such as an Ethernet.

Multiplayer game system 1300 is substantially the same as, and operates in a substantially similar manner to, multiplayer game system 100. However, multiplayer game system 1300 uses a wired system architecture, instead of the wireless architecture of multiplayer game system 100. As multiplayer game system 1300 interconnects game server 110 with the handheld game controllers via a network 1350, there is no need for wireless transmitters and receivers to be located in game arena 120.

The handheld game controllers are designated in FIG. 13 by reference numeral 1335, as they are slightly different to handheld game controllers 135 (described in more detail in relation to FIGS. 6 and 7) in that they do not require a wireless transceiver. Instead, handheld game controllers 1335 rely on a wired connection, such as an Ethernet connection, to network 1350. The wired connection between network 1350 and each handheld game controller 1335 is established through wiring running to each playing station, which in the preferred embodiment is a seat having at least one arm rest. The Ethernet connecting cable may through the armrest and through a mechanical connection which connects the handheld game controller 1335 to the armrest. This mechanical connection may be rigid or flexible.

As the Ethernet connection through network 1350 provides inadequate voltage to power the handheld game controller 1335 during operation of the multiplayer game, handheld game controllers 1335 use a battery power supply when the handheld game controllers 1335 are in use. When the handheld game controllers are not in use, the battery is trickle-charged through the Ethernet connection.

It should be understood that the multiplayer game system 1300 can be substituted for multiplayer game system 100 in relation to the various embodiments described herein, without affecting any of the multiplayer game operations. The primary affect is to the communications between the game server 110 and the handheld game controllers, which is primarily a matter of communications architecture and hardware.

Advantageously, multiplayer game system 1300 obviates the necessity to guard against interference between adjacent game arenas 120, as it does not use wireless communications. On the other hand, multiplayer game system 1300 may be more costly to install in an existing arena, such as a movie theatre, because of the greater structural interference required to install the wired communications infrastructure, compared to the wireless infrastructure of multiplayer game system 100.

Referring now to FIG. 5, a method 500 of conducting a multi-player game is described. Method 500 begins at step 510, at which player registrations are received. Player registrations are received as a result of players indicating (i.e. through appropriate input commands on a handheld game controller 135) their interest in playing a particular multi-player game. Player registration also involves receipt of payment or payment authorization or other means of receiving payment from a player. Player registration is described in further detail below, in relation to FIG. 12.

Once players have registered to play the multi-player game, a game software module is downloaded from game server 110 to the handheld game controller for which a player is registered, at step 515. This game software module is used to facilitate corresponding game activities on the handheld game controller 135 during play of the multi-player game or activities for the player to undertake prior to joining the multi-player game. In an alternative embodiment, step 515 may be performed before step 510 so as to pre-load all of the handheld game controllers 135 with the game software module before initiating the player registration procedure.

Once player registration is complete and the game software download is accomplished, registered players are added to the game at step 520. Depending on the number of registrations received and any predetermined limits on the number of players that may participate in the multi-player game to be played, the first players to register, up to a predetermined cut-off number, will be added to the game. Players registered subsequent to the cut-off number may be provided with an alternate activity while waiting for entry into the game. The cut-off number may be, for example, from 20 to 100 players, depending on the type of game and number of registered players.

Once a sufficient number of registered players have been added to the game at step 520, the game begins at step 530, with only those players added to the game at step 520 being allowed to participate in the multi-player game.

During the course of the game, the avatar controlled by a player will usually suffer some kind of gain or loss, depending upon its experiences within the game, as affected by the other player's avatars and dictated by the game software 310. If an avatar suffers a certain amount of loss or experiences certain predetermined events, the avatar may “die” or otherwise be removed from the multi-player game, in which case the player is no longer an active player in the multi-player game and the player's avatar is no longer visible on the large display screen 425.

Addition and removal of players to and from the game occurs at step 540 whereby, when a player is removed from the game, another player may be added to the game in his or her place. Players registered to play but not yet added to the multi-player game are placed in a queue so as to be added to the multi-player game once other players are removed therefrom. Players removed from the game may join the end of the queue. The first player in the queue is allowed to join the game at the next opportunity. If there are no other players ahead of a player in the queue, that player may join or rejoin the game. In this way, players may be added and removed from the game in quick succession, thus creating interest in the multi-player game while limiting the number of players in the multi-player game so as to avoid obscuring the players' avatars by overcrowding.

Once a player is removed from the game at step 540, he or she may opt to be placed in the queue to re-enter the game at the next opportunity, for example by selecting a corresponding option presented on the handheld game controller 135. Alternatively, the player may opt to perform another activity, such as playing a single player game or using the browser application available on the handheld controller 135.

In one embodiment, while a player is waiting in the queue to rejoin the multi-player game, he or she is provided with a game related activity in order to maintain his/her interest in the multi-player game. For example, this game-related activity may include performing maintenance on the avatar or exchanging or purchasing equipment or tools for a player's avatar. Alternatively, the game-related activity may include a qualification activity, such as a task or target practice, or a team set-up activity, such as selecting positions within the team (as described in relation to FIGS. 14 to 18), for example.

At step 550, game software 310 determines whether the game is finished or whether a time period allotted for playing the multi-player game has expired. If the game has finished or time has expired, the game is ended and a winner is declared at step 560. Otherwise, the game continues, repeating steps 540 and 550 until the game is finished or time expires.

The game may be determined to have finished if one of the players reaches a certain goal or otherwise achieves a winning result in the multi-player game and that player may be declared the winner. Alternatively, a winner of the game may be declared according to an accumulation of achievements or points, for example. If the game ends because of expiry of the allotted time period for the game, the player with the most accumulated points or other achievements may be declared to be the winner. If the game ends but there is further time allowed for playing the game, a new game may be started.

Handheld Game Controller

Referring now to FIGS. 6 and 7, the handheld game controller 135 is described in further detail. Handheld game controller 135 comprises a processor 605 for controlling the operation of handheld game controller 135. Handheld game controller 135 further comprises player input means 610, a wireless RF transceiver 615, a card reader 620, a vibration module 625, memory 630, a power supply module 635, a display screen 640 and audio output means 645. These components are housed in a controller housing 710 (shown in FIG. 7).

Processor 605 may be a fast processor, capable of picture processing, sound processing and fast software algorithm execution as well as control functions and fast input and output functions. One suitable processor is a Sunplus SPG200 processor with a picture processing unit and sound processing unit (with support for NTSC and PAL data formats), which is configurable to receive data inputs from the various player-actuated input means and other inputs, such as the card reader 620 and the RF transceiver 615.

Player input means 610 includes a joystick, at least four action buttons and six to eight other command buttons. The commands and actions associated with these buttons are configurable according to the multi-player game being played. Some of the command buttons may have their functions indicated by adjacent display portions on display screen 640 so that the command buttons may effectively be used to select menu options shown on the display screen 640.

Player input means 610 may also include a touch-sensitive transparent screen overlaid on display screen 640, whereby a player may select a command or option associated with a particular part of the display screen 640 by touching that part of the touch-sensitive screen overlay.

Manipulation of the various player input means, including movement of the joystick, depression of action or command buttons and touching the touch sensitive screen, cause signals to be sent to processor 605, which may be interpreted as command signals or other kinds of input signals. If the player is currently playing the multi-player game, the processor 605 processes these input command signals as necessary and encodes the commands in data packets to be transmitted to game server 110 through RF transceiver 615.

RF transceiver 615 comprises appropriate transmit and receive modules (not shown) with signal conditioning and amplification functions, as well as an antenna (not shown). The RF transceiver 615 is positioned within the handheld game controller 135 so that wireless signal transmission and reception is effected at a peripheral portion of the controller housing 710. In this way, interference of the wireless signals with the workings of other components in the handheld game controller 135 is minimized. A suitable RF transceiver is manufactured by RF Waves, with a RFW-D100 link manager for the RFW112-M transceiver and a dedicated Atmel 89c52 embedded processor.

Card reader 620 may be a magnetic strip card reader for reading paper or plastic cards having an encoded magnetic strip on a face thereof. Once a card is passed through or into card reader 620, so that data stored thereon can be read, the data read from the card is sent to processor 605 for validation. Alternatively, the card reader 620 may be adapted to read smart cards as well as, or instead of, magnetic strip cards.

If the coded data read from the card does not constitute a valid code, processor 605 causes an error message to be displayed on display screen 640, either instructing the player to re-insert the card in to card reader 620 or that the code read therefrom is an invalid code.

If the code read from the card by card reader 620 is determined by processor 605 to be a valid code, this code is encrypted using an encryption algorithm executed by processor 605 and transmitted to game server 110 through RF transceiver 615 and wireless receiver 140. The encryption algorithm may be, for example, a 128 bit WEP, 3DES or RSA algorithm.

Vibration module 625 comprises an offset weight driven by a small DC motor (not shown). The DC motor receives power from power supply module 635 and drives the offset weight, in a revolving manner, in response to receiving an ON signal from processor 605. The ON signal from processor 605 may be applied to the base terminal of a driver transistor, to effectively switch power to the DC motor in response to the ON signal. When the motor drives the offset weight, the arrangement and revolution of the offset weight within handheld game controller 135 causes the entire handheld game controller 135 to vibrate as the offset weight revolves.

Processor 605 is arranged to drive the vibration module 625 in its ON state according to a particular repeating sequence, synchronized with an enhanced visual display of the onscreen avatar on display screen 425, as part of a player character identification process (described in further detail below) actuated by the player by pressing one of the command buttons of player input means 610.

Memory 630 is used by processor 605 for storing computer program instructions comprising a game software module downloaded to handheld game controller 135 (at step 515, as previously described) and for storing application information, including, for example, a browser application, player interface software not specific to any particular game, such as an instant messaging or chat application, and game variables and data received from game server 110 during play of the multi-player game. Memory 630 comprises both volatile and non-volatile memory, including random access memory (RAM) and flash memory. Processor 605 controls the various communications, data processing display and user interface functions by executing the computer program instructions stored in memory 630.

Power supply module 635 may comprise a battery power source, for example in the form of four AA nickel metal hydride (NiMH) rechargeable battery cells, and a power supply regulator circuit for supplying power to processor 605 and other modules. Power from power supply module 635 is controlled by processor 605 so as to provide power to other modules within handheld game controller 135 as necessary. For example, processor 605 switches power from power supply module 635 to provide lighting for display screen 640, power to audio output 645 to cause it to emit sound energy, power to drive the DC motor within vibration module 625, power to the magnetic strip reader within card reader 620 and transmission power for RF transceiver 615. Power supply module 635 may also comprise a charger circuit for recharging the battery cells from an external power source.

In an alternative embodiment, each handheld game controller 135 receives power from an external source, such as an externally mounted battery pack (not shown). In such an embodiment, the external power source supplies power to power supply module 635. The handheld game controllers 135 may each be connected to an arm of a seat or to another fixed structure in the game arena.

The battery pack may be removably mounted to the seat arm or other fixed structure, while the handheld game controller 135 is connected to the seat arm or other structure by means of a tether. The tether comprises a movable connection means for allowing the handheld game controller 135 to move relative to the seat arm or other structure and houses a power cable for supplying power to the handheld game controller 135 from the battery pack. The tether may comprise a rigid connecting arm or may comprise a flexible retractable cable.

Display screen 640 receives output from processor 605 to provide display images. Display screen 640 may be a color super-twist nematic (CSTN) screen, having 320×240 pixel screen resolution and a light emitting diode (LED) backlight.

As previously mentioned above in relation to player input means 610, a touch sensitive screen is overlaid on an outer face of display screen 640 such that the liquid crystal display unit of display screen 640 is separated from the touch-sensitive layer by an appropriate dividing layer, such as glass or transparent plastic. The “touch-screen” thus formed by the touch-sensitive layer overlaid on display screen 640 is arranged to generate an electrical output corresponding to a portion of the touch-screen touched by a player. The touch screen may have a pre-processor (not shown) for receiving the electrical signals and conditioning them, for example by analog to digital conversion, prior to outputting corresponding signals to processor 605. The electrical output from the touch screen is received by processor 605 and is processed to determine whether the player has made a valid selection of an option or game command.

Not all areas of the touch-screen will correspond to valid options or commands and some portions of the touch-screen may become active or inactive at different times, depending on the application being run by processor 605 at any given time. If the selected option or game command is valid, the selected option or command is processed by processor 605 according to the game software module (stored in memory 630) executing on the handheld game controller 135. Such processing may include generating and transmitting one or more packets corresponding to the selected option or command to the game server 110 or may involve displaying further graphics or text stored in memory 630.

The touch screen overlaid on display screen 640 may, in combination with a suitable software application executed by processor 605, advantageously allow instant messaging between the handheld game controllers 135 or 1335. This may be done by providing a user interface comprising buttons on display screen 640 which correspond to a keyboard for allowing the input of message text. The touch screen allows the buttons corresponding to the keyboard keys to be pressed. Such a user interface can be used for text messaging or to enter other text strings, such as a player name, or a team name.

If a player indicates, for example by selecting a menu option, that he or she wishes to transmit an instant message to another player, processor 605 launches an instant messaging application or otherwise provides an instant messaging user interface on display screen 640. Once a player has input the text string to be sent and has identified one or more desired recipients, for example by selecting recipients from a list or selecting a team of players to be the recipient, the processor 605 encodes the text string in one or more packets and transmits the packets to game server 110. Game server 110 then identifies the handheld game controllers 135 corresponding to the intended recipients of the text message, prepares one or more packets containing the text string, together with any other relevant information, such as the sender name, subject, etc., and transmits the packets to the relevant handheld game controllers 135 for display on the respective display screen 640. In this way, a player may communicate to any other player in the multiplayer game, including opponents, allies or prospective allies.

In an alternative embodiment, processor 605 may execute a chat room application for enabling players or other people not participating in the multiplayer game to chat, for example about the game or about an upcoming film. The chat room application uses a similar user interface to that of the instant messaging application. In particular, the chat room application requires a keyboard to be displayed on display screen 640 which, through the touch screen, can be used to input text strings.

Display screen 640 is also used by processor 605 in the player character identification process (described in further detail below in relation to FIGS. 8 to 11), whereby processor 605 causes display screen 640 or a portion thereof to flash synchronously with the vibrations caused by vibration module 625 and sounds emitted from audio output 645.

Audio output 645 comprises at least one speaker for outputting sounds corresponding to certain game events. The sounds emitted from audio output 645 vary depending on the game and the particular game events which occur during play of the multi-player game. For example, sound may be emitted to warn a player that the game time is nearly expired, his or her avatar's health is low or for other scenarios in which the player is to be alerted. One or more standard 8 ohm 250 mW computer speakers may be used for audio output 645.

In FIG. 7, a perspective view of one embodiment of the handheld game controller 135 is shown. The handheld game controller 135 has a housing 710, in the form of a rigid casing, for containing the electrical and electronic components, including processor 605, RF transceiver 615, card reader 620, vibration module 625, memory 630 and power supply module 635. The housing 710 may be molded plastic and of a small size suitable for being lightly and easily cradled by a player's hands.

The housing 710 has a front (or upper) face 712 and a back (or lower) face (not shown). Display screen 640 is located on the front face 712 in a generally central portion of housing 710 so that, when a player holds the handheld game controller 135 in a normal (lateral) playing orientation, front face 712 faces generally upwards and display screen 640 is visible to the player.

Housing 710 includes a left grip 730 and a right grip 732 at opposite left and right lateral ends of the housing 710. Left grip 730 may be formed of a soft yet frictional material, such as rubber, for comfortable gripping by a player's hands during use of the handheld game controller 135. Right grip 732 is formed of the same material, but oppositely disposed and arranged for gripping by the player's right hand. Left and right grips 730, 732 cover the left and right ends of housing 710 while leaving front face 712 substantially unobscured, serving at least a partial shock-absorption function in case the handheld game controller 135 becomes jarred or is dropped.

Player input means 610 is provided in the form of a movement selection member, such as a joystick 720, command (or option) buttons 722 and action buttons 724, as well as a touch sensitive screen overlaid on display screen 640. Joystick 720 is located adjacent left grip 730 in a position suitable for manipulation by a thumb of the left hand when the hand is placed on grip 730 so that the fingers support the lower face of the housing 710 and the thumb may contact the front face 712.

Joystick 720 may be anchored in housing 710 so as to be moveable in any direction through 360 degrees on an X-Y plane. Alternatively, joystick 720 may be anchored so as to only be moveable into predetermined discrete positions on the X-Y plane, for example corresponding to divisions of 45 degrees within the maximum possible 360 degrees. Joystick 720 may be spring-loaded to return to an upright position after deflection by a player in a desired direction. Further, the joystick 720 may have a soft yet frictional material disposed on, or covering, the top surface thereof, for comfortable gripping and easy manipulation by the player.

Action buttons 724 may be disposed adjacent right grip 732, in a position such that they may be easily depressed by a right thumb of the player's right hand when the palm of that hand is placed on right grip 732 and the fingers of that hand support the housing 710 on its back face. Four action buttons 724 are shown in FIG. 7, although it should be understood that greater or fewer numbers of action buttons 724 may be provided on handheld game controller 135. However, for minimum functionality, at least two action buttons 724 should be provided. Each action button 724 will generally provide a different player input command during play of the multi-player game.

Command (or option) buttons 722 may be provided adjacent display screen 640 and intermediate of left grip 730 and right grip 732, as shown in FIG. 7. The command buttons 722 may be disposed along an outer (upper/front) edge of housing 710. There may be six command buttons 722 provided adjacent to a lower edge of display screen 640 so that, by their proximity to display screen 640, they may visually correspond to menu options provided along a lower portion of display screen 640. Instead of being disposed adjacent the lower edge of display screen 640, command buttons 722 may be disposed along an upper edge thereof, or even along a right or left edge thereof.

In FIG. 7, command buttons 722 are shown disposed on a side of housing 710 opposite to a side on which action buttons 724 and joystick 720 are disposed, although command buttons 722 are disposed more centrally of housing 710 and action buttons 724 and joystick 720 are disposed more toward opposite ends of housing 710.

In the embodiment shown, right grip 732 has a slot 740 disposed therein for receiving a card in card reader 620. Card slot 740 is arranged so that a magnetic strip card may be received therein in a swiping action, so that card reader 620 can read data encoded in the magnetic strip on the card. Alternatively, the slot 740 may be disposed in another side of the handheld game controller 135, such as the far or near side edges intermediate the left and right lateral side edges.

In the embodiment shown, left grip 730 has a connector portion 750 therein for receiving a battery recharger or other form of external power supply. Connector portion 750 may be located on another part of the handheld game controller 135, according to the particular desired casing design. For example, the connector portion 750 may be located on the top, bottom or right side or on the lower face of the handheld game controller 135.

Speakers 760 are provided within housing 710 for providing audio output 645. While the location of speakers 760 on housing 710 may vary according to design requirements, it is preferred that they be located on front face 712 in a position where they will not be covered by a player's hands when the player's hands are placed on or around grips 730 and 732.

Advantageously, handheld game controller 135 may be operated in a lateral orientation, where a player's left and right hands are placed around the left and right grips 730, 732, as described above, or in a longitudinal orientation. In the longitudinal orientation, handheld game controller 135 is held by the player so that left grip 730 and right grip 732 are oriented in a longitudinal direction, with left grip 730 being closest to the player and right grip 732 being further from the player. In such an orientation, the player's left hand remains generally positioned on left grip 730, while the player's right hand is moved more centrally so that the player's fingers support the back face of housing 710 underneath display screen 640 and the thumb of the player's right hand is positioned to be able to press command buttons 722. The player's left hand continues to be positioned so as to manipulate joystick 720 by the left thumb. In the longitudinal presentation, display screen 640 is also oriented longitudinally.

Depending on the particular game or other function to be performed by the handheld game controller 135, it may be preferable to operate the handheld game controller 135 in the longitudinal orientation, rather than the lateral orientation. However, handheld game controller 135 is generally intended for use in the lateral orientation.

Player Avatar Identification

Referring now to FIG. 8, a method of player character (or avatar) identification 800 is described. Avatar identification is initiated by the player, at step 810, by pressing one of the command buttons 722. Alternatively, a dedicated action button 724 may be provided for actuating the avatar identification request. Advantageously, the player may actuate the avatar identification request at any time the player chooses. This function is particularly helpful to the player in situations where a large number of avatars are present on the primary display of the multi-player game or, for example, where the player's avatar has become engaged in combat with another avatar and the player becomes confused as to which avatar it is that the player controls.

In response to a player actuating the avatar identification request on the handheld game controller 135, processor 605 transmits an avatar identification request packet to the game server 110, at step 815. In response to receipt of the avatar identification request packet from the handheld game controller 135, game server 110 sends a synchronization packet back to handheld game controller 135, in order to synchronize display of an enhanced visual representation of the avatar on the large display screen 425 with sensory output from the handheld game controller 135. The synchronization packet specifies a particular repeating sequence to be output as vibration-by-vibration module 625, sounds from audio output 645 and as a repeating visual display (for example, such as one or more flashing icons) on display screen 425.

At step 820, the game server sets a time period for providing the visual indication and corresponding synchronized sensory output by which the player can recognize his/her corresponding avatar on the display screen, at step 825. This time period is notified to the handheld game controller 135 by inclusion of appropriate data in the synchronization packet.

At step 830, an enhanced visual indication of the avatar (corresponding to the handheld game controller 135 from which the avatar identification request packet originated) is displayed on display screen 425. This enhanced visual indication may be provided in any of a number of ways, including, for example, repeatedly enlarging and shrinking the image of the avatar according to the particular repeating sequence or providing a flashing pointer, halo or icon above, below or otherwise adjacent to the avatar. In a further example, if a player has registered a user name or a team name, that name may temporarily appear or flash above, below or otherwise adjacent to the avatar on display screen 425.

Simultaneously with step 830, step 835 is performed, in which a synchronized sensory output is provided to the player from handheld game controller 135. This sensory output includes a repeating vibration sequence corresponding to the repeated flashing or other enhanced visual indication on display screen 425. Additionally, the sensory output includes a repeated sound sequence corresponding to the vibration sequence and flashing visual indication on display screen 425. Optionally, display screen 640 on handheld game controller 135 may flash in a corresponding repeating sequence.

The sensory output from handheld game controller 135 in a particular repeating sequence aids the player in identifying the appropriate avatar on display screen 425, as the player is able to match the repeating sequence received from the handheld game controller 135 with the visually repeating sequence on display screen 425.

Both game server 110 and processor 605 repeatedly cause the display screen 425 and handheld game controller 135 to provide the enhanced visual indication and sensory output until the time period for doing so expires, at step 840. Once the relevant time period has expired, the enhanced visual indication and sensory output is ceased at step 845 and, if the player wishes to continue to receive the enhanced visual indication and sensory output, the player must again actuate the avatar identification request at step 810 on handheld game controller 135.

In one embodiment of the avatar identification method 800, display screen 640 may display a low resolution version of the game environment in which the player's avatar is located, so as to indicate the location of the avatar relative to the game environment and the other player's avatars. In such a low-resolution display, the player's avatar may be represented by a simple icon, such as a colored block, shown relative to other avatars, represented by blocks of other colors. Alternatively, the low resolution display on display screen 640 may point out the player's avatar thereon by surrounding it with a halo, pointing to it with an arrow or otherwise providing graphics to provide an indication to the player of the avatar's location within the game environment.

The low-resolution display may also shows the game environment in an alternative view to that provided on display screen 425. For example, the low-resolution display on display screen 640 of handheld game controller 135 may be an aerial view of the game environment, whereas display screen 425 in game arena 120 may provide a view of the game environment from a ground-based perspective.

In this alternative embodiment, in order for handheld game controller 135 to display a low-resolution version of the game environment, it must be pre-loaded with appropriate low-resolution graphics for display when appropriate. Such low-resolution graphics may be retrieved from memory 630 at appropriate times or specifically in response to receipt of the synchronization packet from game server 110 at step 820. An example of such a low-resolution display on screen 640 is provided in FIG. 11C.

Example Game Displays

Referring now to FIGS. 9, 10 and 11A-11C, example game displays of the multi-player game are described in further detail. FIG. 9 shows an example game environment 900 displayed on large display screen 425 during play of the multi-player game. Avatars 910 controlled by players of the multi-player game are shown within game environment 900.

In the example game environment 900, many player avatars 910 are shown in the context of a sporting game. In order for a player to discern his/her avatar among the many avatars displayed, he/she may choose to actuate the avatar identification request button or option provided on handheld game controller 135 (the process for which is described above in relation to FIG. 8). In the example game environment 900, one such player has elected to actuate avatar identification request and that player's character is provided with an enhanced visual indication which, in this example, takes the form of arcuate halo icons 920 bracketing the front and back of the player's avatar 910.

In one embodiment of the multi-player game system 100, players may elect to form teams, whereby their player avatars 910 may join together and compete against other teams. In such an embodiment, the enhanced visual display provided in response to the avatar identification request may also extend to indicating player avatars belonging to the team of which the actuating player is a part. In example game environment 900, player avatars of the same team as the actuating player are shown with indicator icons 925 positioned adjacent the relevant player avatars (including the avatar of the player making the avatar identification request).

It should be understood that many different game environments may be created for facilitating multi-player games according to the methods and systems described herein. Accordingly, the present invention is not limited to any of the specific examples shown and described herein.

Referring now to FIG. 10, a single player activity display 1000, as provided by display screen 640 of handheld game controller 135, is shown. Single player activity display 1000 has a game action display portion 1052 and a game information display portion 1054. The game action display portion 1052 shows a player avatar 1070 (which may be different to the player avatars shown in the multi-player game) performing an action controlled by player input to the handheld game controller 135. Player activity display portion also includes other active display elements, such as game statistics or metrics 1072. Game information display portion 1054 includes a score display 1060 and directions 1062 for performing the single player activity, possibly including graphics and appropriate icons. Score display 1060 may be an individual score or, if the player is playing as part of a team, score display 1060 may show the team score.

A player may undertake a single player activity, for example such as that depicted in FIG. 10, white waiting for entry (or re-entry) into the multi-player game or as a selected adjunct activity to be performed as one of several tasks to be completed to achieve the goals of the multi-player game.

Referring now to FIGS. 11A, 11B and 11C, a further example game scenario having a game environment 1100 is shown. Player avatars 1110 move about the game environment 1100, competing with each other to achieve one or more objects of the game, for example, such as destroying each other, traversing the game environment in a certain manner or scoring points. In the example game environment 1100, each player controls an avatar in the form of a vehicle. Each vehicle has certain equipment, resources and parameters (such as life/health/condition points).

A secondary game display 1150 of the relevant equipment, statistics and condition of the player's vehicle avatar may be provided on display screen 640 of handheld game controller 135. If the player is part of a team, team information will be provided, along with the equipment, statistics and condition of the avatar 1110, as part of an information display portion 1154 of secondary display 1150. In this example, no activity display portion (like activity display portion 1052 in FIG. 10) is provided, although in alternative game scenarios, such a display may be provided as part of secondary display 1150.

Referring to FIG. 11C, a reduced resolution display 1180 may be displayed on the display screen 640 of handheld game controller 135 in response to player actuation of the avatar identification request, as previously described. In the present exemplary game environment 1100, the corresponding low-resolution display 1180 of the player's avatar 1110 provides a low-resolution icon 1185, located centrally in display 1180 and seen in aerial view within the game environment. An enhanced visual indication 1190 is provided around the icon 1185 corresponding to player avatar 1110. Simultaneously with display of low-resolution display 1180 on display screen 640, the player's avatar 1110 is shown within the game environment 1100 on large display screen 425 as having an enhanced visual appearance, such as a halo or flashing pointer or icon.

Payment Processing

In preferred embodiments, payment is received from each participating player at the multi-player game prior to that player being allowed to play the game. In an alternative embodiment, the multi-player game may be played for free. For example, where a new film is to be released in cinemas, a multi-player game having a theme similar to that of the new film may be provided in the cinema prior to release or screening of the film, for promotional purposes.

According to preferred embodiments, players wishing to play the multi-player game must pre-register to create a personal debit or credit account or purchase a pre-paid account. As an exception to this, a player may provide credit card details to a handheld game controller 135 once in the game arena 120 and, if the credit card is authorized for payment, a temporary account may be created for that player. Alternatively, credit card information may be supplied by players with personal or pre-paid accounts, in order to continue or rejoin the multi-player game after their initial credit is used up. Where necessary, payment/authentication system 220 is used to communicate with credit card authorities to effect a debit of the credit card account.

Referring now to FIG. 12, a method of player registration, including player payment processing, is described. The method of player registration is designated by reference numeral 1200 and begins at step 1205 with prompting a player to input a payment authorization code. This prompt is provided on the display screen 640 of handheld game controller 135 and allows the player to manually input a payment authorization code (for example by providing a numerical keypad on the display screen 640 so that the player can input numbers through the touch-screen) or to insert a card having the payment authorization code stored thereon into the card reader 620. The manual input of the payment authorization code may be used, for example, to input a credit card number if the card reader 620 is not able to read the credit card or to input another unique number such as a player account number.

Multi-player game system 100 may be set up to allow players to pre-register an account (through the administrative server system 210) either as a credit account or a debit account, so that the player can register for a game when in the game arena 120 by inputting his/her account number (or other identifying information, such as a PIN) into the handheld game controller 135 to authorize debiting of his/her player account.

As an alternative to having a pre-established registered player account, a new player may either purchase a certain amount of playing credits or playing time by inputting valid credit card details or by purchasing a pre-paid generic account. For example, the pre-paid account may have ten playing credits or a dollar value associated therewith, which any player having the account details can use to play the multi-player game. This pre-paid account may have a magnetic strip card associated therewith or a unique identification code which the player has to enter into the handheld game controller 135 as the payment authorization code in order to register for the multi-player game.

Step 1205 may be performed in response to a player attempting to manipulate, or otherwise provide input to, the handheld game controller 135, for example such as by pressing a button, moving the joystick, inserting a card into the card reader 620 or touching the touch-sensitive screen. Following display of the prompt on display screen 640 at step 1205, the handheld game controller 135 awaits receipt of the payment authorization code at step 1210.

Once the payment authorization code is received at step 1210, the code is checked, at step 1215, for validity. This validity check is used to verify that the payment authorization code is of a type that may be a valid code, for example by checking the number of digits in the code, checking that the code is internally consistent (i.e. where the code allows error detection) or for other parseable errors.

If the code received from the player is determined at step 1215 to be invalid, the handheld game controller 135 displays an error message on display screen 640 at step 1220 and the player is again prompted to input a valid payment authorization code at step 1205. If the code is determined at step 1215 to be valid, the processor 605 proceeds to encrypt the code at step 1225 using an encryption algorithm stored in memory 630. Encryption is used to provide security protection of the payment authorization code, which may contain credit card information or other sensitive information, against interception during transmission from the handheld game controller 135 to the game server 110.

At step 1230, the encrypted code is transmitted to game server 110 via RF transceiver 615, wireless receivers 140 and communications controller 115. At step 1235, game server 110 decrypts the payment authorization code using a corresponding decryption algorithm to the encryption algorithm employed by handheld game controller 135 at step 1225.

At step 1240, the game server 110 checks whether the code decrypted at step 1235 is a code corresponding to a registered account. This checking is performed by comparing the decrypted code with a database of pre-existing accounts, both those for which pre-paid accounts may be bought by anonymous users and for full player registrations having a debit or credit account.

If the decrypted code is not recognized (as corresponding to a personal or pre-paid account) by the game server 110 at step 1240, game server 110 may refer the code to an external credit authority, for example where the code resembles a credit card number, to effect a debit transaction. If sufficient funds are not in the account, either the credit card account or the multi-player game account, as determined at step 1250, then, at step 1255, the game server 110 transmits a message back to handheld game controller 135 to display an error message to the player, at step 1220. The player is then prompted to input a valid payment authorization code at step 1205.

If, at step 1250, sufficient funds are determined to be in the player's account, the relevant account is debited for a predetermined amount at step 1260. Once the player's account has been debited, the game server 110 transmits a message to the handheld game controller 135 from which the encrypted code was received that the payment transaction has been completed and to unlock the input means of the handheld game controller 135, at step 1265. Prior to step 1265, efforts by a player to manipulate the handheld game controller 135 or otherwise provide input thereto will not be processed unless that input is provided in relation to the prompt for the payment authorization code at step 1205. In this sense, the controls of the handheld game controller 135 are “locked” prior to step 1265. After step 1265, those controls become “unlocked”.

Once the player's account is debited at step 1260, the player is effectively registered to play the multi-player game (or perform another selected activity). Steps 1260 to 1270 thus correspond generally to steps 510 and 515 described previously in relation to FIG. 5.

After the unlocking of the handheld game controller at step 1265, game server 110 proceeds to download one or more software modules to handheld game controller 135, at step 1270. The one or more software modules thus downloaded will generally include a game module, but may include other software modules as necessary. In a selection step (not shown), the game module is requested by the player where, in one embodiment, at least one single player game is available for selection by the player in addition to at least one multi-player game.

In an alternative embodiment, where the player is only allowed to play a particular preselected multi-player game, the step of allowing the player to select the desired game is omitted. In this embodiment, the downloading of the software modules takes place before player registration commences. The downloading can thus be performed by broadcasting the data making up the game and other software modules to all of the handheld game controllers 135 at the same time, in order to avoid unnecessarily using valuable bandwidth during the player registration process.

In an alternative embodiment, the various decryptions, account registration and debiting functions may be carried out by the administrative server system 210, instead of by game server 110. In a further alternative, some of those functions may be shared between the game server 110 and the administrative server system 210 in order to distribute processing load.

In preferred embodiments, the multi-player game system 110 is configured to allow players to select from several activities to be performed using the handheld game controller 135. One of these activities is playing a multi-player game, which is the primary purpose of the system. However, the system also advantageously allows players to entertain themselves by selecting alternative activities to the multi-player game. This allows the system to have a broader appeal than that which would be provided by only allowing a single activity to be performed.

Additionally, the multi-player game system 100 and multi-arena game system 200 may be configured to allow registered players to vote on which of a plurality of available multi-player games should be played in a game arena 120. Such a voting process may occur between steps 1265 and 1270, as described above in relation to FIG. 12.

Team Play

Referring now to FIGS. 14 to 18, further embodiments of the game are described, which particularly facilitate team play of the multi-player game. In the team play embodiments, several players share a single avatar on the main display screen 425. For example, the avatar may be a vehicle piloted and operated by the various members of the team, each using the team member's own handheld game controller 135.

FIG. 14 is a flow diagram illustrating a method 1400 of facilitating team play among players of the multiplayer games. Exemplary screen displays associated with the team play embodiments of the invention are shown in FIGS. 15 to 18. These exemplary screen displays are displayed to individual players on the display screen 640 of respective handheld game controllers 135 during the team formation stage of the multiplayer game.

Following registration with the multiplayer game system 100 (or 1300), a player may be provided with the option to play as part of a team or to play solo. If the player elects to engage in team play, the player is shown an initial selection display 1500, such as is shown in FIG. 15. Display 1500 provides the player with buttons (which can be selected or pressed by touching the touch screen or by using the joystick 720 to move a cursor over the desired button and pressing one of the function buttons 724) for creating a new team or joining an existing team. Create team button 1510, if selected, will cause the handheld game controller 135 to display further screens, corresponding to steps in the team formation process, such as are shown on FIGS. 16, 17 and 18. A join team button 1520, if selected, causes display screen 640 to display a list of already created teams that are open to new team members and which the player can select from to request to join.

Team formation method 1400 begins at step 1410, when a player selects create team button 1510. The player creating the team is automatically appointed to be the captain of the team and is given control over the membership and of the type of avatar which is to represent the team on the large display screen 425. The player that creates the team is also a member of the team and is allowed to choose a certain position or role within the team.

In response to selection of the create team button 1510, handheld game controller 135 asks the player to input a team name, after which the handheld game controller 135 communicates a team creation request, including the team name, to game server 110. Game server 100 then creates a new team entry in a table of teams, using the team name, according to a predetermined data structure, which is described in further detail below. The team names entered in the table of teams are stored and maintained by game server 110 and are provided by game server 110 to a player that wishes to join a team, upon selecting join team button 1520.

When a player requests to join a team, at step 1420, by selecting from the list of open teams, the team captain is notified of the request to join the team and a team formation display 1600 is displayed to the team captain. Display 1600 relates to team formation and provides information and selection buttons for that purpose.

Display 1600 comprises a display description field 1605, a team name field 1610 showing the team name, a team list 1620 and, if a player has requested to join a team, a join request 1630. Display 1600 also comprises a start button 1670 for enabling the team captain to indicate that team formation is complete.

Team list 1620 comprises a list of the players' names for the players that are already on the team, as well as showing empty team positions. For each player shown in team list 1620, there is a corresponding player removal button 1625 which, if selected by the team captain, will cause the corresponding player to be removed from the team. Upon removal from the team, the player removed will be notified of the removal and will be returned to display 1500.

Team list 1620 may also indicate a rank associated with a player, where the rank may be indicative of the player's experience level or previous achievements as a registered player in the multiplayer game. Greater game-related avatar attributes may be associated with high rank, thus giving a player incentive to repeatedly play the game and strive to reach a higher rank.

Join request 1630 comprises a text field notifying the team captain of the join request, text fields 1640 showing the player's name and rank, an accept button 1650 and a reject button 1660. If the team captain selected the accept button 1650 at step 1430, the join request is accepted and the requesting player is added to the team at step 1450. If the team captain selects reject button 1660 at step 1430, the player requesting to join the team is notified of the rejection of the request at step 1440 and is returned to display 1500.

The team captain views display 1600 during team formation at step 1420 when there are join requests 1630 to be accepted or rejected by the team captain. Otherwise, the team captain may choose to select an avatar for the team by viewing an avatar selection display 1700, shown in FIG. 17. Display 1700 comprises a description or instruction field 1705, a team name field 1710, an avatar image 1715, a team list 1720 and an avatar attribute description 1730. Team list 1720 shows the team members currently in the team and their currently allocated or chosen roles or positions within the team. Avatar attribute description 1730 includes an avatar name and lists or describes or graphically represents the game related attributes of the avatar corresponding to the avatar images 1715 currently displayed on display 1700. For example, the avatar may have certain attributes relating to speed, offensive capabilities, defensive capabilities, agility, or special abilities.

Display 1700 further comprises a back button 1750, a forward button 1760 and a select button 1770 for scrolling through various different avatar images 1715 and selecting an avatar having the desired attributes. Select button 1770 may be selected by the team captain to select the chosen avatar at step 1460 when the avatar image 1715 for that avatar is visible on display 1700.

Once a team avatar has been selected, each of the team members can view a role selection display 1800, an example of which is shown in FIG. 18, and select a desired role or position 1820 on the team, at step 1470. Display 1800 comprises a text description or instruction field 1805 a team name field 1810, an avatar image 1815, a number of positions or roles 1820 located on or in relation to the avatar image 1815 and a number of text fields 1830 corresponding to the positions or roles 1820. Each role or position 1820 may be occupied by a single team member but there cannot be more team members than there are available roles or positions 1820. On the other hand, it is not necessary for all roles or positions 1820 to be occupied by a team member. Team members may opt to change roles or positions 1820 at any time during the game, although the team avatar chosen by the captain cannot be changed once the game begins. Text fields 1830 contain a description of the role or position 1820 and the name of the player, if any, occupying that role of position 1820.

Display 1800 also comprises a back button 1850 for allowing a player to return to a previous display and a start button 1870, which is visible only to the team captain, for indicating that the team is ready to play the game. When the team captain selects start button 1870 or another game initiation event occurs, such as expiry of a predetermined time limit, the team enters the game at step 1480.

Avatar image 1815 corresponds generally to the avatar selected in display 1700. Depending on the avatar selected in display 1700, avatar image 1815 may vary and may provide for varying roles or positions 1820, including varying locations or functions of the role with respect to the avatar.

As described previously in relation to FIG. 6, handheld game controllers 135 or 1335 can be used for instant messaging between players. This is particularly advantageous in a team context, in which team members may wish to send comments or instructions to other team members. As previously mentioned, instant messaging is facilitated through an instant messaging application executed by processor 605. Thus, a player may use the instant messaging application to transmit messages to teammates or other players, such as prospective teammates or opponents or prospective allies.

In one embodiment, processor 605 may also execute software which facilitates voting amongst members of a team, for example in order to select a team avatar. The voting may be initiated by the team captain or another team member. Such a voting process is performed in a similar manner to instant messaging, in that the player initiating the vote effectively initiates transmission of an instant message to each of the other team members.

When game server 110 receives a vote initiation request from a player (via that player's handheld game controller 135), game server 110 transmits a formatted message to each of the intended recipients (i.e. the initiating player's teammates) and a voting display is displayed on display screen 640, requesting the player to cast a vote. The voting display provides a number of selection buttons to enable the voting player to make a selection and initiate a response message back to game server 110 containing the selection.

Game server 110 collates the voting responses and notifies the team members of the outcome of the vote. If game server 110 does not receive a reply from each player within a predetermined time period, the game server 110 can determine the outcome of the vote without the input of some of the players. In case of a tied vote, the captain's vote may determine the outcome.

If, during the game, a team avatar dies or is otherwise removed from the game, the team avatar ceases to be displayed on large display screen 425. If the team wishes to rejoin the game, the captain may choose another avatar. Alternatively, the team may choose the new avatar through the voting process described above. In embodiments employing a single team avatar, all of the team members are removed from the game when the team avatar dies and, assuming that all players wish to remain part of the team, the team rejoins the game together with the same or newly selected avatar. As described previously in relation to FIG. 5, the game may allow for only a limited number of avatars to be displayed on the large display screen 425 at any one time. Accordingly, teams wishing to rejoin the game may have to wait in a queue before being allowed to rejoin.

In one embodiment of payment processing, each player has his or her account debited for each time the player joins or rejoins the game. Accordingly, if a team rejoins a game after being removed, each of the players on the team is debited a predetermined amount corresponding to the amount debited for joining the game or a reduced amount for rejoining the game.

While FIGS. 15 to 18 provide example displays relating to team formation aspects of the multi-player game, it should be understood that further displays may be provided as necessary in order to further facilitate team formation, avatar selection of team member roles. Further, the example displays in FIGS. 15 to 18 are shown in relation to a pirate game motif, where the team members occupy certain roles on a pirate ship, with the ship being the single team avatar visible on large display screen 425. It should be understood that other motifs or themes may be used as the basis for multiplayer gaming, including team-based participation. For example, a tank or plane of other form of vehicle may be used for the avatar within a corresponding military or other battle theme.

Alternatively, the team members may operate as a team without sharing a single avatar. For example, each team member may have a single avatar corresponding to a soldier on a battlefield or a sportsman on a sports field. In such cases, the visual and functional form of the player avatars may be dictated by their roles on the team.

Once the team has been formed, the avatar chosen and the multiplayer game begun, all of the avatars for each of the teams are displayed on large display screen 425, together with the avatar of any player who elected to play as an individual. The avatars available for selection by solo players may be different to those available to teams of players. For example, the avatars of solo players may be smaller and have less offensive or defensive capabilities than the team avatars.

Regardless of whether an avatar is representative of an individual or a team, the avatar identification functions described above in relation to FIGS. 8 to 11 operate in the same way. Further, for team avatars, each player may be visible on the team avatar according to the player's position or role within the team. Using the pirate ship example illustrated in FIGS. 15 to 18, a player may be shown to be manning a canon, for example by showing a small colored square or halo or other indicator at a canon on the avatar corresponding to the team member's location on the team avatar. During game play, team members may be able to view display 1800 on display screen 640 so that they can readily check their positions on the team avatar and can readily change positions, if necessary.

During team play, each player's manipulations of his or her respective handheld game controller 135 are encoded by processor 605 in one or more packets and transmitted to game server 110, which processes the actions of each of the players in the team separately and as part of the team.

in order to manage the team play, game server 110 implements a server side data structure, an example of which is shown in Table 6 below. The data structure comprises a team table for tracking all of the teams and a player table for tracking each player in the various teams. Each team and player has its own record in the data structure. The records in the server side data structure are updated frequently by game server 110. A corresponding data structure (of reduced size) is maintained by each handheld game controller 135 or 1335 and used in communications with game server 110.

In another embodiment of the multiplayer game system, players are allowed to join the multiplayer game through a remote connection, without being located in the game arena. Such a multiplayer game system is depicted in FIG. 19 and designated by reference numeral 1900. In multiplayer game system 1900, game server 110 communicates with handheld game controllers 135 via communications controller 115 (not shown) as previously described in relation to FIGS. 1 to 4 and 13 and displays a primary display of the multiplayer game on display system 125. In addition to receiving game input from handheld game controllers 135, game server 110 may receive game input from remote game controllers 1910 located remotely from the game arena 120 and game server 110 over a communications connection 1920 through a network 1930.

Remote game controllers 1910 may be desktop or laptop personal computers or video game consoles, for example. Remote game controllers 1910 have game software 1940 installed and running thereon, in order to play the multiplayer game. Game software 1940 is downloaded from gamer server 110 or administration server system 210 and installed on game controller 1910 by a prospective player of the multiplayer game.

Each remote game controller 1910 has associated therewith a display 1950, for example such as a television connected to the video game console or as part of the desktop or laptop computer system, for viewing images of the multiplayer game. In order that the images on display 1950 are sufficiently current to enable real time play of the multiplayer game, the communications connection 1920 between game software 1940 and game server 110 needs to be of a relatively high speed.

In response to game-related user input into remote game controllers 1910, game software 1940 transmits data packets representative of the game related commands arising from the user input to game server 110 via network 1930. Game server 110 provides data packets in return to game software 1940 over network 1930 to update the game status and enable game software 1940 to generate updated game images for display on display 1950.

Multiplayer game system 1900 enables players to join in the multiplayer game from home or another location remote from the game arena 120 in which the multiplayer gaming mainly occurs. Players joining the multiplayer game through remote game controllers 1910 may join as solo players or may participate in a team. In one embodiment, players manipulating remote game controllers 1910 are only permitted to join the game using a single avatar, rather than a shared avatar. Such players may form a team or alliance with other players but do not share a team avatar. In such an embodiment, the game images viewed by the remote player on display 1950 correspond to the view from the perspective of that player's avatar. This first person perspective is in contrast to the global view of the multiplayer game visible on the large display screen 425 in game arena 120. Optionally, remote players manipulating remote game controllers 1910 may be able to toggle between a first person perspective and a global view.

It should be understood that game server 110 may be implemented as a server system having a large number of processors for handling the potentially large number of players that may participate in the multiplayer game.

The bingo engine 2120 comprises a random number generator 2210, a bingo logic module 2220, an active game database 2230, a card library 2240 and a verification module 2250. The game management module 2110 communicates directly with the random number generator 2210 and the bingo logic module 2220. The card library 2240 stores all the unique serialized bingo cards. The active game database 2230 stores the information necessary to allow the bingo logic module 2220 to keep track of the cards in play during a particular game of bingo.

When directed by the game management module 2110, the random number generator 2210 selects a number to be played. This number is passed to the bingo logic module 2220, which checks all the active cards in the active game database 2230 for matching numbers. Each matching number is recorded as such in the active game database 2230. Each player having a game card with the selected number then marks their own game card on the handheld game controller 135 using a touch screen or other input device.

The random number generator 2210 will continue to select numbers until a player has met the criteria for winning. For example, in order to win, a player may need to have a game card with a line of selected numbers, a box of selected numbers or a blackout in which all the numbers on a players game card have been selected. When a player believes they have a winning game card, they may indicate this to the game server 2010 using an input component on the handheld game controller 135 or through other means. Once a player has indicated that they have a winning game card, this will be verified by the verification module 2250 of the bingo engine 2120. If the verification module 2250 determines that the indicated game card is a winner then the game is finished. Otherwise, the game will continue.

The game system 2000 shown in FIG. 20 relates to embodiments in which the multi-player bingo game may be performed in a single game arena 2020.
